CHORD READING:The numbers on the dots in the chord diagrams below indicate the finger positioning:1 = index finger, 2 = middle finger, 3 = ring finger, 4 = pinkyThe “x” on top of the diagram means you “mute” that particular string.“O” means an open string.

Additional beginner chord types include the F chord and the Bm chord.
The "F and Bm" shapes are more challenging, but they are a great follow
up to the basics and are also common chords in nearly every style of
music.
Note: The F chord is played with your index
finger barring two strings on the first fret. This is a bit tricky in
the beginning, but with daily practice you will develop this technique.
